Note - I also tried bu not using wsi.xml file but not luck because compliance is set to no in back end.

Api.php ##

<?php
class Mycompany_Mymodule_Model_Folder_Api extends Mage_Api_Model_Resource_Abstract
{        
        public function myapimethod( $message)
        {
            return "This is the message: ".$message;
        }
}

V2.php ##

<?php
class Mycompany_Mymodule_Model_Folder_Api_V2 extends Mycompany_Mymodule_Model_Folder_Api
{   

}

Note - Also tried including helper folder and Data.php file and referring in config.xml but still not luck.

Can someone please check what I am missing here....

Let me know if any more information is needed.

Thanks Siddharth

Answer 1

I can not help you with the "resource path is not callable" issue, but I would assume that it has something to do with you developing in a local XAMPP environment.

For the problem with the helper that is not found:

You have to un-comment the helper-classification in your config.xml and rename the "Helperasdasd"-folter to "Helper"; in there must lay a file called Data.php with the class declaration:

<?php

class MyCompany_Mymodule_Helper_Data extends Mage_Core_Helper_Data {}

This is enough for the contents of this file.

Also, in the api.xml file, everywhere you use module="mymodule", update this to exactly the name of the helper-config-path in the config.xml; you are on Windows I guess, and thus it may not be case sensitive. on every other system, it is. Additionally, I don't believe Windows is officially supported my Magento.

Answer 2

Finally I am able to resolve issue....After much head scratching and comparing my files back and forth with core api files

First as you said, I have updated all config files with exactly same name(considering case senstivity) of files/folders.

Still i was getting same error, not sure how but Then I realized that a closing global tab .. was missing in config.xml file :( :(

And bang it worked liked charm....Thanks

Let me know if anybody needs updated files.

[Edit] - Missed to mention - also renamed helper folder and reffered it in config.xml, this actually i tried before but didn't worked then...may be it worked because of putting names exactly same.

Thanks Siddharth
